If it was a 302 with a 4 inch bore and a 3 inch stroke with 8 pistons, you could go up safely to around 4800-5000 rpm because the piston strokes are an inch shorter. Past that, I'd want the motor balanced and better flowing heads.

The key to remember here, is that the 300 doesn't rev high safely because it doesn't have too. All of it's power is on the down low, which is where you should keep it when having fun.

Peace.
